Android：禁用用于调试构建的 crashlytics

Question

I just wanted to disable crashlytics for debug build.

So I followed the instruction in their official document. https://docs.fabric.io/android/crashlytics/build-tools.html

According to the document, I have to do followings so I did it. First I added below,

android {
buildTypes {
    debug {
      // Disable fabric build ID generation for debug builds
      ext.enableCrashlytics = false
      ...

And I added below into my Application class.

// Set up Crashlytics, disabled for debug builds
Crashlytics crashlyticsKit = new Crashlytics.Builder()
.core(new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build())
.build();

// Initialize Fabric with the debug-disabled crashlytics.
Fabric.with(this, crashlyticsKit);

But I still get this error.

     Caused by: io.fabric.sdk.android.services.concurrency.UnmetDependencyException: This app relies on Crashlytics. Please sign up for access at https://fabric.io/sign_up,

Is there something that I'm missing?

I checked that the build type that I was trying to build and it worked well before without this configuration.

My crashlytics version is 2.9.4.

implementation 'com.crashlytics.sdk.android:crashlytics:2.9.4'

Thanks!

To disable Firebase before your application starts, you need to add the following code to your AndroidManifest.xml:

<application
    ... >

    ...

    <meta-data
        android:name="firebase_crashlytics_collection_enabled"
        android:value="${crashlyticsCollectionEnabled}" />

</application>

The expression ${crashlyticsCollectionEnabled} is called manifest placeholder and its value comes from your main module's build. gradle file:

android {

...

buildTypes {
    debug {
        manifestPlaceholders = [crashlyticsCollectionEnabled:"false"]
        ...
    }

    release {
        manifestPlaceholders = [crashlyticsCollectionEnabled:"true"]
        ...
    }
}

}

Looks like you are missing API Key , if yes then add in manifest file under application tag, like below

<application
      .........
      .........
      <meta-data
          android:name="io.fabric.ApiKey"
          android:value="<FABRIC_API_KEY>"
      />
</application>

Well, now that I look at your code it looks like there is definitely a better solution for that than the way I am doing it, but the approach I am using works very well so I will share it anyway (I am using only two build types: DEBUG and RELEASE and no variants, so it is sufficient for me). I am simply not initializing the Crashlytics altogether (in MyApp#onCreate ) when BuildConfig.DEBUG == True

public class MyApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        if (!BuildConfig.DEBUG) {
            Fabric.with(this, new Crashlytics());
        }
    }
}

But I am sure somebody else with come up with better solution.

In your app level build.gradle add this :

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

dependencies {
    compile('com.crashlytics.sdk.android:crashlytics:KIT_VERSION@aar') {
        transitive = true;
    }
}



android {
    buildTypes {
            release {
                shrinkResources true
                minifyEnabled true
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
            debug {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            }

        }
    productFlavors {
        production {
            buildConfigField 'boolean', 'IS_FABRIC_DISABLED', 'false'
        }
        fabricOn {
            buildConfigField 'boolean', 'IS_FABRIC_DISABLED', 'false'   
        }
        fabricOff {
            buildConfigField 'boolean', 'IS_FABRIC_DISABLED', 'true'           
        }
    }
}

Add below line in your application class onCreate method:(note: this is in kotlin convert it to java)

val core = CrashlyticsCore.Builder().disabled(BuildConfig.IS_FABRIC_DISABLED).build()
Fabric.with(this, Crashlytics.Builder().core(core).build())

After adding this you will see in left side Build Variants with diffrent option. (here I didn't apply fabric option it shows default option)
